The Ethereum Virtual Machine (EVM) is the runtime environment for smart contracts in Ethereum. It is a 256-bit register stack, designed to run the same code exactly as intended. It is the fundamental consensus mechanism for Ethereum. The formal definition of the EVM is specified in the Ethereum Yellow Paper.[34][37] On February 1, 2018, there were 27,500 nodes in the main Ethereum network.[38] Ethereum Virtual Machines have been implemented in C++, Go, Haskell, Java, JavaScript, Python, Ruby, Rust, Elixir, Erlang, and soon, WebAssembly (currently under development).
Physical wallets store the credentials necessary to spend bitcoins offline and can be as simple as a paper printout of the private key;[7]:ch. 10 a paper wallet. A paper wallet is created with a keypair generated on a computer with no internet connection; the private key is written or printed onto the paper[g] and then erased from the computer. The paper wallet can then be stored in a safe physical location for later retrieval. Bitcoins stored using a paper wallet are said to be in cold storage.[99]:39 In a 2014 interview, QuadrigaCX founder Gerald Cotten explained that the company stored customer funds on paper wallets in safe deposit boxes: "So we just send money to them, we don’t need to go back to the bank every time we want to put money into it. We just send money from our Bitcoin app directly to those paper wallets, and keep it safe that way."[100]
من منظور المنقبين فإن سعر البيتكوين الحالي أقل بكثير مما يجب عليه أن يكون، ولهذا ستجد أنه لا رغبة لديهم في بيع العُملات التي بحوزتهم بأسعار مُنخفضة لأنهم قد استخدموا كميات هائلة من الكهرباء لإنتاجها، إضافة إلى الاستثمار في عتاد خاص للقيام بذلك. الوضع سيزداد سوءا بالنسبة إليهم ما لم ينخفض عدد المُنقبين بشكل مُعتبر، حيث أن عدد العُملات التي سيتم إنتاجها ستنخفض إلى النصف كل 4 سنوات. في المقابل، تم إنتاج كميات كبيرة من البيتكوينات بشكل رخيص جدا في بدايات العُملة لما كان عدد المُنقبين قليلا ولما كان عامل “الصعوبة” hardness منخفضا جدا، وبالتالي حاجة إلى كهرباء أقل، هذا الأمر خلق حالة من اللاتوازن داخل شبكة العُملة، حيث بإمكان أصحاب البيتكوينات القديمة بيع عُملاتهم دون تسجيل خسائر مُقارنة بمن انضموا إلى جبهة المُنقبين مؤخرا.
The domain name "bitcoin.org" was registered on 18 August 2008.[17] On 31 October 2008, a link to a paper authored by Satoshi Nakamoto titled Bitcoin: A Peer-to-Peer Electronic Cash System[4] was posted to a cryptography mailing list.[18] Nakamoto implemented the bitcoin software as open-source code and released it in January 2009.[19][20][11] Nakamoto's identity remains unknown.[10] 

In the blockchain, bitcoins are registered to bitcoin addresses. Creating a bitcoin address requires nothing more than picking a random valid private key and computing the corresponding bitcoin address. This computation can be done in a split second. But the reverse, computing the private key of a given bitcoin address, is mathematically unfeasible. Users can tell others or make public a bitcoin address without compromising its corresponding private key. Moreover, the number of valid private keys is so vast that it is extremely unlikely someone will compute a key-pair that is already in use and has funds. The vast number of valid private keys makes it unfeasible that brute force could be used to compromise a private key. To be able to spend their bitcoins, the owner must know the corresponding private key and digitally sign the transaction. The network verifies the signature using the public key; the private key is never revealed.[7]:ch. 5

Ethereum’s core innovation, the Ethereum Virtual Machine (EVM) is a Turing complete software that runs on the Ethereum network. It enables anyone to run any program, regardless of the programming language given enough time and memory. The Ethereum Virtual Machine makes the process of creating blockchain applications much easier and efficient than ever before. Instead of having to build an entirely original blockchain for each new application, Ethereum enables the development of potentially thousands of different applications all on one platform.
Various journalists,[205][210] economists,[211][212] and the central bank of Estonia[213] have voiced concerns that bitcoin is a Ponzi scheme. In April 2013, Eric Posner, a law professor at the University of Chicago, stated that "a real Ponzi scheme takes fraud; bitcoin, by contrast, seems more like a collective delusion."[214] A July 2014 report by the World Bank concluded that bitcoin was not a deliberate Ponzi scheme.[215]:7 In June 2014, the Swiss Federal Council[216]:21 examined the concerns that bitcoin might be a pyramid scheme; it concluded that, "Since in the case of bitcoin the typical promises of profits are lacking, it cannot be assumed that bitcoin is a pyramid scheme." In July 2017, billionaire Howard Marks referred to bitcoin as a pyramid scheme.[217]

The "Metropolis Part 1: Byzantium" soft[citation needed] fork took effect on 16 October 2017, and included changes to reduce the complexity of the EVM and provide more flexibility for smart contract developers. Byzantium also added supports for zk-SNARKs (from Zcash), with the first zk-SNARK transaction occurring on testnet on September 19, 2017.[citation needed]
The overwhelming majority of bitcoin transactions take place on a cryptocurrency exchange, rather than being used in transactions with merchants.[138] Delays processing payments through the blockchain of about ten minutes make bitcoin use very difficult in a retail setting. Prices are not usually quoted in units of bitcoin and many trades involve one, or sometimes two, conversions into conventional currencies.[32] Merchants that do accept bitcoin payments may use payment service providers to perform the conversions.[139]
The unit of account of the bitcoin system is a bitcoin. Ticker symbols used to represent bitcoin are BTC[a] and XBT.[b][72]:2 Its Unicode character is ₿.[1] Small amounts of bitcoin used as alternative units are millibitcoin (mBTC), and satoshi (sat). Named in homage to bitcoin's creator, a satoshi is the smallest amount within bitcoin representing 0.00000001 bitcoins, one hundred millionth of a bitcoin.[2] A millibitcoin equals 0.001 bitcoins; one thousandth of a bitcoin or 100,000 satoshis.[73] 

Another type of physical wallet called a hardware wallet keeps credentials offline while facilitating transactions.[106] The hardware wallet acts as a computer peripheral and signs transactions as requested by the user, who must press a button on the wallet to confirm that they intended to make the transaction. Hardware wallets never expose their private keys, keeping bitcoins in cold storage even when used with computers that may be compromised by malware.[99]:42–45
Bitcoin, along with other cryptocurrencies, has been described as an economic bubble by at least eight Nobel Memorial Prize in Economic Sciences laureates, including Robert Shiller,[193] Joseph Stiglitz,[194] and Richard Thaler.[195][14] Noted Keyensian economist Paul Krugman wrote in his New York Times column criticizing bitcoin, calling it a bubble and a fraud;[196] and professor Nouriel Roubini of New York University called bitcoin the "mother of all bubbles."[197] Central bankers, including former Federal Reserve Chairman Alan Greenspan,[198] investors such as Warren Buffett,[199][200] and George Soros[201] have stated similar views, as have business executives such as Jamie Dimon and Jack Ma.[202]
While another less aggressive soft fork solution was put forth, the Ethereum community and its founders were placed in a perilous position. If they didn’t retrieve the stolen investor money, confidence in Ethereum could be lost. On the other hand, recovering investor money required actions that went against the core ideas of decentralization and set a dangerous precedent. 

Ethereum-based customized software and networks, independent from the public Ethereum chain, are being tested by enterprise software companies.[48] Interested parties include Microsoft, IBM, JPMorgan Chase,[33][49] Deloitte,[50] R3,[51] Innovate UK (cross-border payments prototype).[52] Barclays, UBS and Credit Suisse are experimenting with Ethereum blockchain to automate Markets in Financial Instruments Directive (MiFID) II requirements.

يقصد بتعدين البتكوين هو استخراجه وتنقيبه ولتبسيط المفهوم فالعملية تشبه استخراج الذهب، الذهب لاستخراجه من باطن الأرض يتطلب معدات معينة مخصصة لذلك الغرض وجهد كبير، الأمر مشابه لتعدين البتكوين فهو يتطلب معدات وبرامج مخصصة تقوم بفك الشفرات والعمليات الحسابية المعقدة ، هذه البرامج مجانية على الانترنت تستطيع تعدين البيتكوين الان على جهازك ولكن للاسف جهازك مهما كانت قوته لن يستحمل الضغط الكهربائي الهائل وسيصاب بالتلف أضف إلى ذلك فاتورة الكهرباء التي ستتسبب بها ، احد الحلول يكمن في التعدين السحابي وهذا التعدين السحابي وهو يتمثل ببساطة أن شركات متخصصة في المجال وتسمى بالمسبح (بالانجليزية: Pool) وهو أن يجتمع مجموعة من الأشخاص لهم نفس الهدف كل يدفع نسبة من المال عبارة عن استثمار وعند الربح يأخذ المال على حسب النسبة التي وضعها.


The price of bitcoins has gone through cycles of appreciation and depreciation referred to by some as bubbles and busts.[159] In 2011, the value of one bitcoin rapidly rose from about US$0.30 to US$32 before returning to US$2.[160] In the latter half of 2012 and during the 2012–13 Cypriot financial crisis, the bitcoin price began to rise,[161] reaching a high of US$266 on 10 April 2013, before crashing to around US$50. On 29 November 2013, the cost of one bitcoin rose to a peak of US$1,242.[162] In 2014, the price fell sharply, and as of April remained depressed at little more than half 2013 prices. As of August 2014 it was under US$600.[163] During their time as bitcoin developers, Gavin Andresen[164] and Mike Hearn[165] warned that bubbles may occur.

David Golumbia says that the ideas influencing bitcoin advocates emerge from right-wing extremist movements such as the Liberty Lobby and the John Birch Society and their anti-Central Bank rhetoric, or, more recently, Ron Paul and Tea Party-style libertarianism.[132] Steve Bannon, who owns a "good stake" in bitcoin, considers it to be "disruptive populism. It takes control back from central authorities. It's revolutionary."[133]
In 2016 a decentralized autonomous organization called The DAO, a set of smart contracts developed on the platform, raised a record US$150 million in a crowdsale to fund the project.[25] The DAO was exploited in June when US$50 million in ether were taken by an unknown hacker.[26][27] The event sparked a debate in the crypto-community about whether Ethereum should perform a contentious "hard fork" to reappropriate the affected funds.[28] As a result of the dispute, the network split in two. Ethereum (the subject of this article) continued on the forked blockchain, while Ethereum Classic continued on the original blockchain.[29] The hard fork created a rivalry between the two networks.

Lightweight clients consult full clients to send and receive transactions without requiring a local copy of the entire blockchain (see simplified payment verification – SPV). This makes lightweight clients much faster to set up and allows them to be used on low-power, low-bandwidth devices such as smartphones. When using a lightweight wallet, however, the user must trust the server to a certain degree, as it can report faulty values back to the user. Lightweight clients follow the longest blockchain and do not ensure it is valid, requiring trust in miners.[96]
Both blockchains have the same features and are identical in every way up to a certain block where the hard-fork was implemented. This means that everything that happened on Ethereum up until the hard-fork is still valid on the Ethereum Classic Blockchain. From the block where the hard fork or change in code was executed onwards, the two blockchains act individually.

Bitcoin is pseudonymous, meaning that funds are not tied to real-world entities but rather bitcoin addresses. Owners of bitcoin addresses are not explicitly identified, but all transactions on the blockchain are public. In addition, transactions can be linked to individuals and companies through "idioms of use" (e.g., transactions that spend coins from multiple inputs indicate that the inputs may have a common owner) and corroborating public transaction data with known information on owners of certain addresses.[120] Additionally, bitcoin exchanges, where bitcoins are traded for traditional currencies, may be required by law to collect personal information.[121] To heighten financial privacy, a new bitcoin address can be generated for each transaction.[122]


Though transaction fees are optional, miners can choose which transactions to process and prioritize those that pay higher fees.[77] Miners may choose transactions based on the fee paid relative to their storage size, not the absolute amount of money paid as a fee. These fees are generally measured in satoshis per byte (sat/b). The size of transactions is dependent on the number of inputs used to create the transaction, and the number of outputs.[7]:ch. 8

While it’s still early days, Mist, MetaMask and a variety of other browsers look set to make blockchain-based applications accessible to more people than ever before. Even people without a technical background can now potentially build blockchain apps. This is a revolutionary leap for blockchain technology that could bring decentralized applications into the mainstream.

As the industry continues to investigate blockchain platforms, it’s apparent that Ethereum is becoming a de facto leader. For example, a few days ago JPMorgan publicly open-sourced its Quorum platform, architected and developed around the Go Ethereum client by Jeff Wilcke and his team. Several other major banks are using Ethereum, and Microsoft is anchoring its Bletchley platform on it as the foundational blockchain element. Industry, both publicly and confidentially, continues to contribute to Ethereum and work with us and others to help our promising, toddler-age codebase reach maturity. Stay tuned for news on this front.

Bitcoin is a digital asset designed to work in peer-to-peer transactions as a currency.[4][135] Bitcoins have three qualities useful in a currency, according to The Economist in January 2015: they are "hard to earn, limited in supply and easy to verify."[136] Per some researchers, as of 2015, bitcoin functions more as a payment system than as a currency.[32]


بيتكوين ليست العملة الافتراضية الوحيدة المتواجدة حاليًا في الأسواق الافتراضية. فقد برزت بفضل نجاحات ال بيتكوين ، مجموعة متنوعة من ما يسمى ب "altcoins" أو العملات الافتراضية البديلة ذات قيمة جيدة في الأسواق. أهم الفروقات بين البيتكوين وهذه العملات البديلة هي: البتكوين الأصعب في التعدين والأكثر غلاءً بينما العملات البديلة يمكن الحصول عليها عادةً بطريقة أسهل وأرخص، ويمكن أن يكون سعرها أكثر ثباتًا من سعر البتكوين ذات السعر المتقلب، كما أنّ الكثير من هذه العملات تم إنشاؤها لتلافي المشاكل الحاصلة في نظام بتكوين.[20] هذه لائحة بست عملات رقمية بديلة :

The U.S. federal investigation was prompted by concerns of possible manipulation during futures settlement dates. The final settlement price of CME bitcoin futures is determined by prices on four exchanges, Bitstamp, Coinbase, itBit and Kraken. Following the first delivery date in January 2018, the CME requested extensive detailed trading information but several of the exchanges refused to provide it and later provided only limited data. The Commodity Futures Trading Commission then subpoenaed the data from the exchanges.[181][182]

Despite the fallout from The DAO hack, Ethereum is moving forward and looking to a bright future. By providing a user-friendly platform that enables people to harness the power of blockchain technology, Ethereum is speeding up the decentralization of the world economy. Decentralized applications have the potential to profoundly disrupt hundreds of industries including finance, real estate, academia, insurance, healthcare and the public sector amongst many others.
تتمتع عملة البيتكوين بقدر عالٍ من السرية. مبدئيا الأمر صحيح، حيث أن كل ما تحتاجه لإرسال بعض البيتكوينات لشخص آخر هو عنوانه فقط. لكن بحكم أنه يتم تسجيل كل عملية تحويل في سجل بيتكوين فإنه بالرغم من عدم معرفتك لهوية مالك أي عُنوان إلا أنه بمقدورك أن تعرف كم عدد البيتكوينات التي في حوزته وما هي العناوين التي أرسلت بيتكوينات إليه. إن قام أحدهم بالإعلان صراحة عن امتلاكه لعناوين بيتكوين مُعينة فإنه سيُصبح بإمكانك معرفة ما هي العناوين التي قامت بإرسال بيتكوينات إليه وما هي العناوين التي أرسل إليها بيتكوينات. الكشف عن عنوان البيتكوين الخاص بك ليس مُستبعدا، حيث أنك ستحتاج إلى إعطائه لغيرك في حال ما إذا احتجت أن يرسلوا لك بعض المال إليه. يُنصح باستخدام عناوين مُختلفة لعمليات تحويل مُختلفة للحفاظ على مُستوى مُعين من المجهولية، رغم ذلك هناك الكثيرون ممن لا يقومون بذلك. من الناحية التقنية يبقى تتبع مصدر بعض العمليات المشبوهة على شبكة بيتكوين مُمكنا، حيث يكفي تتبع عمليات التحويل إلى غاية وصولها إلى عنوان معروفة هوية صاحبه، وحينها يكفي القيام بعمليات تحقيق عكسية إلى غاية الوصول إلى صاحب الحساب المشبوه. صحيح بأن كم البيانات المُتعلقة بجميع عمليات التحويل ضخم، إلا أن قوة الحواسيب في تزايد مُستمر وإمكانية تتبع هذه العمليات واردة جدا، بل ويُمكن الجزم بأنه تتبع عمليات سرقة البيتكوينات أسهل بكثير من تتبع سرقة الأموال على هيئتها الورقية.
Ethereum is the pioneer for blockchain based smart contracts. When running on the blockchain a smart contract becomes like a self-operating computer program that automatically executes when specific conditions are met. On the blockchain, smart contracts allow for code to be run exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. It can facilitate the exchange of money, content, property, shares, or anything of value. The Ethereum network went live on July 30th, 2015 with 72 million Ethereum premined.
طرح شخص أطلق على نفسه الاسم الرمزي ساتوشي ناكاموتو فكرة بيتكوين للمرة الأولى في ورقة بحثية في عام 2008،[2] ووصفها بأنها نظام نقدي إلكتروني يعتمد في التعاملات المالية على مبدأ الند للند (بالإنجليزية: Peer-to-Peer) ، وهو مصطلح تقني يعني التعامل المباشر بين مستخدم وآخر دون وجود وسيط (كالتورنت). يقول القائمون على بيتكوين إن الهدف من هذه العملة التي طرحت للتداول للمرة الأولى سنة 2009 [3] هو تغيير الاقتصاد العالمي بنفس الطريقة التي غيرت بها الويب أساليب النشر.[4] وفي عام 2016 أعلن رجل الأعمال الأسترالي كريغ رايت أنه هو ساتوشي ناكاموتو مقدما دليلا تقنيا على ذلك ولكن تم كشف زيف أدلّته بسهولة.[5]
تسمح تطبيقات بيتكوين والتي يُطلق عليها أحيانا اسم عميل بيتكوين للمُستخدمين بالتعامل مع شبكة بيتكوين. في شكله القاعدي يسمح التطبيق بتوليد وحفظ مفاتيح خاصة بالمُستخدم والاتصال بشبكة الند للند الخاص بالعُملة. تم إطلاق أول تطبيق بيتكوين سنة 2009 من طرف ساتوشي ناكاموتو مُؤسس عُملة بيتكوين كتطبيق مجاني ومفتوح المصدر. يُستخدم هذا التطبيق -والذي يُطلق عليه عادة اسم تطبيق ساتوشي- كمحفظة على الحواسيب الشخصية للقيام بعمليات دفع إلكترونية أو كخادوم لاستقبال تلك المدفوعات ولخدمات أخرى مُتعلقة بالدفع. أما تطبيق Bitcoin-Qt فيتم اعتباره كتطبيق مرجعي بحكم أنه يُمثل الآلية التي يعمل من خلالها بروتوكول بيتكوين ويُعتبر مثالا يُحتذى به لغيره من التطبيقات. لدى القيام بعمليات شراء باستخدام الهواتف الذكية فإنه عادة ما يتم استخدام تطبيقات بيتكوين تقوم بتوليد و/أو قراءة QR codes لتسهيل مهمة التحويل والدفع. كما تتوفر حاليا عدة تطبيقات تعمل كخواديم تقوم بتأكيد الإجراءات التي تتم على الشبكة وتقوم بإضافتها كتلة تحويلات.

The bitcoin blockchain is a public ledger that records bitcoin transactions.[75] It is implemented as a chain of blocks, each block containing a hash of the previous block up to the genesis block[c] of the chain. A network of communicating nodes running bitcoin software maintains the blockchain.[32]:215–219 Transactions of the form payer X sends Y bitcoins to payee Z are broadcast to this network using readily available software applications.


سعر البيتكوين غير مستقر ومن المُحتمل جدا أنك سمعت بأخبار تجاوز بيتكوين لحاجز 11000 دولار صعودا أو نزولا. هناك من يعتقد بأن هذا السعر مُبالغ فيه، لكن هناك كثيرون يعتقدون بأنه سعر لا يُعطي للبيتكوين حقه. من بين الأسباب التي تدفع إلى اعتقاد ذلك هو كون البيتكوين سلعة تحتاج إلى قدر كبير من الكهرباء لإنتاجها ويُفترض أن يكون سعرها على الأقل مُقاربا لسعر الكهرباء التي تم استهلاكها لإنتاجها أو أعلى بقليل بحكم قيام المُنقبين بدور حيوي لشبكة بيتكوين، وبالتالي يجب أن يكون هناك ما يدفعهم للقيام ذلك. بإمكاننا معرفة ما يربحه المنقبون من العمليات التي يقومون بها بشكل دقيق، حيث هناك مواقع تنشر هذه الإحصائيات جاهزة، لكن يُمكن التحقق من ذلك عبر تحليل سجل حسابات بيتكوين أيضا. لدى كتابة هذه السطور استطاع المُنقبون تحقيق $3,925,863 خلال الساعات الـ24 الماضية، قد يبدو هذا المبلغ ضخما، لكن القيام بعمليات التنقيب تلك احتاجت إلى 11,388,578 جيجا هاش /الثانية وهو أيضا رقم كبير جدا ويحتاج إلى قدر ضخم من الكهرباء للقيام بذلك. ليس من السهل معرفة تكلفة القيام بذلك لكن يُمكن القيام ببعض الحسابات التي ستعطينها فهما تقريبيا للوضع.
To lower the costs, bitcoin miners have set up in places like Iceland where geothermal energy is cheap and cooling Arctic air is free.[205] Bitcoin miners are known to use hydroelectric power in Tibet, Quebec, Washington (state), and Austria to reduce electricity costs.[204][206] Miners are attracted to suppliers such as Hydro Quebec that have energy surpluses.[207] According to a University of Cambridge study, much of bitcoin mining is done in China, where electricity is subsidized by the government.[208][209]
